I don't know what that command is outputting, but typically the output of OpenSSL commands is an ASN.1 structure which may, for example, contain the algorithm identifier, identifying which algorithm was used for encryption. The increased size could also be a padding factor, for example padding out to the nearest 8-byte boundary.

Apologies if this is a duplicate. I am wondering why the file size grows by 8 bytes when doing openssl des-ecb -nosalt -in infile -out outfile -K $Key -iv 0 -p What is in those 8 extra bytes? Is this a bug or a feature?
